Zero no Shinjitsu (ゼロの真実)

Zero’s Truth: Forensic Medical Examiner Matsumoto Maou

You killed my mother?

Your mother was a goddess. I have no reason to kill a goddess.

I was sentenced for killing 3 men.

Dr. Indene.

Where were you 8 years ago?

Why did you lie to Mao-kun 8 years ago?

You perverted that kid!

Kosugi Sadao killed three persons.

He killed them on account of you?

Indene Kyoko is a liar. Don't trust that woman.

What's the link between her and that inmate?

You know more than you let on?

Tell me about that inmate on death-row.

You met Kosugi 178 times in Tokyo Detention Center…

What do you do that for?

I was the first to interrogate Kosugi.

In August 8 years ago…

Kosugi Sadao came to the Police Department to surrender.

He said: I'm a killer.

You're a professor in a famous university?

Why did you kill?

Well…

Don't try to fool the police.

I don't know the name.

I didn't come here to answer questions…

Then why?

I want to die.

An intellectual without much sense.

They don't give the death penalty so easily.

But if I told you I killed 3 men?

3 men?

Mamiya Manabu, 1991.

Maruyama Kyosuke, 2000.

Asao Ryuta, 2006.

He admitted to killing those 3.

But the motive of the murders…

He had no connection, never spoke with them.

But we had no suspect, and Kosugi knew details about the murders.

And about the place and circumstances.

While there was no eyewitness.

We also found the 3 weapons at his place.

This is my sentence.

The defendant will be punished by death.

Kosugi listened to the trial in silence…

He also refused a lawyer.

This case made the headlines "University Professor serial killer".

He posed as a gratuitous murderer acting for fun.

But Kosugi, I'm sure, had a solid motive.

I'm sure he was linked somehow to his victims.

Whatever Kosugi achieved with those 3 murders remains a mystery.

We found neither purpose nor relationship.

The case was closed eight years ago.

I have no interest in Kosugi.

So why do you go visit him?

You're… related to Kosugi?

Tell me the truth.

There's nothing we can change but…

I want to know about my mother.

Your mother?

My mother was a student with Professor Kosugi.

It seems she worked in the lab with him at the Faculty of Science and Technology.

You're Kosugi's daughter?

I do not know. Kosugi denied it.

My mother gave me up at birth.

16 year later…

My mother suddenly wished to reconnect with me.

At that time I was in the United States…

To check her DNA…

I made a temporary stay in Japan.

But……

But the day we were supposed to meet.

My mother died.

At the age 16…

The first time I saw my mother, was as a corpse.

That was August 12, 2006.

That was 1 week before Kosugi killed Asao Ryuta.

She fell from the roof of the General Hospital…

And died instantly from the fall.

Cause of death: fracture of the cervical spine.

Is it a murder or a suicide or an accident?

The the post-mortem report could not establish it.

They didn't find…

.

Good morning. Good morning.

Unidentified man.

Burned body discovered in a building on fire.

There has been 3 arsons in Toshima the same day.

There's been only one death, the other arsons were minor.

There's just one person we can't find from that burnt building…

Suzumoto Kentaro, 36, his blood type matches that of this body.

You mean this man was surprised in his sleep?

I'm starting.

I decide when it starts.

I'm starting. -Thank you.

Thank you.

Oh…

I'll do that, you're just an assistant.

Reply! -Yes.

Tsk!

Apart from the burning, there are no traumas.

One spot is not burnt.

Pink color from Postmortem lividity.

That Pink color means he died of carbon monoxide asphyxiation?

That's right.

You're bothering us.

Sorry. -I'm opening the airway.

Music.

Almost no soot in the aiareway.

Huh? -He didn't inhale soot.

He was dead when the fire burned him.

Huh?

How can an inspector be so dense?

He dies of carbon monoxide inhalation.

Then the fire reached his room.

I examine the blood. -Why?

For carbon monoxide concentration.

No need. We know he died of carbon monoxide poisoning.

Hosaka-san. -Yes.

Check his blood type, quickly. -Yes.

I'll hurry.

I check the lungs.

who's the surgeon here?

I'm telling you to wait for orders!

Listen to people!

Kiyoshi, Good luck. -We know why he died.

No need to spend extra time.

Just for your fun.

The organs could reveal something. -He died of carbon monoxide poisoning.

There's no point in further cutting that body.

Dr. Iwamatsu do you agree? -What?

Dr. Nakayama am I right?

Since you're a surgeon your opinion should suffice.

Please Dr. Indene, say something.

Can't you decide?

You're bothering everyone…

Take organ samples while you're at it.

I take out the liver.

Hopeless…

There, there… Dr. Indene.

He went to the toilet.

A little beep.

What?

Yeah?

What's with this girl?

What's with this team?

What's with me?

Thank you so much.

Carbon monoxide hemoglobin saturation, 80%.

We knew what it was, why did you need the lab?

Lab test cost to the tax payers.

You all turn into 'chief's.

Kiyoshi is long in the toilet.

Where do we go for lunch?

I'd like the pig bowl at Tonton-tei. How about cold noodles?

Chief likes greasy food…

Cold noodles won't satisfy him.

You okay Dr. Iwamatsu?

Take a break too Matsumoto.

Hosaka-san too. Yes.

You too. -(Tomita) What?

There's a hole in the stomach.

Huh?

Gastric acid has melted the membrane, the content has leaked.

What does that mean? -Autophagy.

Autophagy? What does that mean? -Autophagy.

Autophagy?

This person didn't die in the fire.

Music.

I checked with his parents in Fukui the teeth record confirms the identity.

The burned body is definitely Suzumoto Kentaro.

It's terrible for the parents.

He died of carbon monoxide poisoning yet…

It's not concerned to the arson in the building.

Uh? -(Nakayama) Why?

Destruction of organs was already quite advanced.

What do you mean by that?

While the person is alive the mucosa of the stomach is protected…

From the attack of gastric acid.

There's a balance between attack and defense.

At death the protective function is no longer performed.

Gastric acids melt the mucosa.

This is called autophagy.

However, when the body is burnt the mucosa hardens…

Autophagy stops.

Had Suzumoto died in the fire from carbon monoxide poisoning…

The fire would have burnt the body…

Too soon for the autophagy to occur.

The autophagy was so advanced that at least…

3 hours had elapsed since Suzumoto's death…

And then the fire occurred.

Considering carbon monoxide caused death…

What's the difference?

Just change the estimated time of death, and we close the file.

We haven't determined yet if it was murder, suicide or accidental death.

Why did the poisoning occur before the fire?

The police will do that. How many times do I have to remind you?

Since we took the organ samples our mission stops here.

What Matsumoto is doing, you take from here and do your police job.
